The frida gold coin earrings from lady luks are solid 925 sterling silver (nickel free) with 1 micron 14ct yellow gold plated. Length: 4cm. This is a modern take on the drop earring. This piece utilises the fibonacci symbol, science and nature as one and also uses the golden/silver bead. This means it works perfectly with the frida range. A versatile piece that is fine enough to wear from day into evening. Jewellery comes in beautiful gift packaging.
